Post-Tensioning Applications On Bridges & Viaducts

The most common types of structures where post-tensioning applications have been used from past to present are bridges and viaducts. The main reason for this is the large support spans of these structures and the heavy design and service loads on them. In bridges and viaducts designed with post-tensioning systems, it is possible to cross spans of 100-120 m by using much fewer piers.

The use of Post-Tensioning Systems, especially in inclined or curved bridge and viaduct structures with wide pier spans, not only facilitates construction, but also allows for a significant reduction in the materials and workmanship since thinner cross-sections can be built with the post-tensioning method.
